General information:
The voltage regulator 1702.3702-01 is purposed for voltage
maintenance of the onboard vehicle network in predetermined
limits in all system operation modes of electrical equipment
at change of the rotation frequency of the alternator rotor,
electrical load and environment temperature.
Applicability: automobiles VAZ-2108, -09, -10 (with carburetor), VAZ-21213,
"Oka" with the alternator 37.3701 or its modifications.
The voltage regulator 1702.3702-01 is a functionally improved
analog of the regulator 1702.3702*.
The automobile voltage regulator 1702.3702-01 is a regulator
of the highest class. The regulator output switch is made
under MOSFET technology owing to that the losses of power
given off in the form of heat have been sharply lowered; the
regulator reliability has been enlarged. The heating of the
regulator relative to environment temperature is less than
5°C which allowed to provide the exact characteristic of the
regulating voltage thermal compensation.
Due to usage of the additional wire, voltage on the alternator
is maintained directly on the alternator output terminal.
Herewith are reached the highest parameters of the current
velocity and load characteristics. It prolongs battery life
cycle, provides optimal operating modes of all using equipment
increasing thus reliability of all automobile electrical equipment.
The regulator is produced in a single climatic design О2.1
in accordance with GOST 15150 for internal market and for
export. On extent of protection against penetration of foreign
bodies and water, the item meets design IP68 in accordance
with GOST 14254. All electrocontact connecting elements of
the regulator are made of brass rolling with galvanic cover
that guarantees reliability of the electrical connections
during all service period. An operating mode of the regulator
is S1 in accordance with GOST 3940.
The regulator is mounted directly on the alternator where
the setting of regulators 1702.3702-01 and 1702.3702 with
the help of standard screws is stipulated, the additional
wire is fixed on the standard screw of a circuit "30".
It is not recommended to set the voltage regulator 1702.3702-01
on the alternators in the automobiles with the electrical
circuit that differs from the typical one. An indication of
misfit to the circuit diagram or alternator type is a shortage
of wire length, operation of the engine is possible after
ignition cutoff.
The warranty period of exploitation is 3 years from the date
of commissioning or from the date of sale in retail commercial
network. The warranty obligations of the manufacturer are
valid during 4 years from the date of the item production.
The date of production is marked on the case of the item.
* - 1702.3702 - “metal cube“. It is manufactured by great number of manufacturers.
It is not protected against moisture. It was excluded out of application many
years ago because of low endurance to climatic influence
